My motherboard provides 4x USB 3.2 Gen1 ports for rear I/O and another 2x USB 3.2 Gen1 ports for front I/O (through the header), but my chipset only supports 2x USB 3.2 Gen1 ports. Where is the support for the other ports coming from?

The motherboard is an ASRock B450M Steel Legend

    Huh that’s interesting, I believe that GPU should’ve been running at x8 with that CPU, but if it works then whatever I suppose.

    I believe there are PCIe bandwidth benchmarks, if you really want to confirm, but I wouldn’t worry.

    Also it isn’t uncommon for the device to just report the wrong speed, for example my Intel Arc reports running at x1, but benchmarks show otherwise.
